16" x 25" MERV 11 Filter Media

The GeneralAire 4366 is a 16" x 25" x 4", MERV 11 rated air filter media cartridge, and is the correct filter replacement for Honeywell F100 Series and Honeywell F150 Series Media Style Air Cleaners. This General Aire filter media consists of electrostatically charged synthetic material that dramatically reduces airborne particulates to provide healthier indoor air. These GeneralAir filter cartridges capture airborne particles as small as 1.0 micron then traps them deep within the layers of spun-bonded fibers. The General Air OptiFiber media is hydrophobic, so it does not absorb moisture. It is also shredding resistant, assuring reliable and dependable dust-fighting capabilities. Features: Moisture resistant frame remains sturdy even in high humidity Rust resistant galvanized wire downstream gives the filter rigidity and holds media in place after installation Built-in support fingers hold pleats in place and allow for maximum dust holding Foam gasket helps seal the filter into the air cleaner and prevents dust from bypassing the filter
